To all whom it may concern.'

Be it known that I, ALBERT C. FISCHER, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Revoluble Engines,of which the following is a specification.

This invention relates t-o a revoluble wheel tire and has reference to awheel or engine having a non-revoluble, central annular frame to providebearings for a revoluble tire, `useful as a band-wheel or for tractionor other purposes, one of its objects being to apply a driving power ator near the periphery of the tire.

rI`he invention consists of the novel construction, combination andarrangement 0f parts as described herein and claimed, and as illustratedin the accompanying drawing, wherein,

yFigure 1 is a view of the device in side elevation, parts being brokenaway andgin section. Fig. 2 is a, sectional view of the samelongitudinally of the tire. Fig. 8 is a sectional view through the wheelon line 3 3 of Fig. 2. Fig. 4 is a transverse section on line 4 4 ofFig. 2. Fig. l5 is a transverse sect-ion on lin'e 5 5 of Fig. 2. Figs. 6and 7 are enlarged, detail views showing a clutch. Fig. 8 is a sectionalview on line 8 8 of Fig. 2. Fig. 9 is a Sectional view on line 9 9 ofFig. 2. Fig. 10 is a broken away view of the engine or wheel" in sideelevation to illustrate means for readjusting the pistons and forexpelling exhaust gases. i

While the invention is illustrated and described in connection with theexpansive force of ignited gas as aY source of power, I do not wish tobe understood as limiting myself in this respect, nor to size, form,

l proportion or minor details of construction further than determined bythe scope of the appended claims.

In the drawing, which illustrates one embodiment of the invention, Ihave shown a non-rotatable support consisting, in part, of a centralbracket l provided with a spindle 2 upon which, by means of keys 3, issecured a hub 4 having radially disposed spokes arranged in pairs, asthe pairs '5, 5, and 6, 6 and the pair 7, 7, the outer ends of the sspokes being provided with a rim or annular tire-support 8; the hub,spokes and rim thereby providing a non-revoluble wheelmember or support.Numerals 9 indicate a pair of bearing-blocks which are stationary withrespect to the rim and Which project outwardly of the ends Vof thespokes 7 and 7 At 10 is indicated an annular casing or tire,substantially of U-shape in cross-section,its end Walls or sides beingadapted to engage numerous balls or rollers 1l which are disposed insuitable grooves formed in the opposedannular recesses 12 of the rim 8,and means are provided to cause a revoluble movement of the tire on saidbearings, consisting in part, of the pair of segmental cylinders 13 andv14, these being secured within and at diametrically opposed parts of thecasing, each being provided with a central, longitudinally curved tube15.

A two-faced ring gear 16 is provided and is disposed substantially atthe middle of the tire, within and movable through the tubes 15. It isadapted to have bearings upon balls or rollers 17 which are interposedbetween the inner part of the ring gear and the bearing-blocks 9. Asbest shown in Fig. 3, idler gears are employed in pairs and arranged inthe tire, as the `pairs 18 and 19, the gears for each pair beingdisposed upon opposed sides and engaging the ring gear, and mounted inthe blocks 9 for rotation, said gears also engaging the opposed annularracks 20 of the tire.

Numerals 21 and 22 respectively indicate curved pistons and curvedpiston rods for the cylinders. Each piston rod is of tubular form andcircumscribes and is adapted to have slidable movements Ona tube 15.Also each piston rod is provided at its outer end witha clutch, bestshown in Figs. 6 and 7, each clut-ch consisting, in part, of a housing23 secured to a piston rod by a keeper 24.- disposed in a slot 25 formedin the housing. Numeral 26 indicates a paWl foreach clutch, said pawlbeing provided with a tail-piece having an inclined face orcontacting-part a, and it will be understood that when a piston isactuated for moving a piston rod outwardly of a cylinder, the piston rodmay have a limited movement within the housing 23 for engaging theinclined part a. of the pawl to thereby move the tooth ot the pawl intoengagement with the ring gear., the outward movements, in alternation,ot the piston rods and the pawls, operating to move the ring gear. Whena upiston begins its movement inwardly of a cylinder the pawl will bereleased from the ring gear on account of the form or inclination ot'its inner wall 7), said wall being disposed at an obtuse angle. to thelongitudinal axis of the tooth.

Hydrocarbon is conducted to each cylinder in alternation by actuation ofthe pistons. At 2T (Fig. 9) is indicated a passageway formed in thebracket 1 in communication with any suitable source ot' gas fuel supplyand in communication with the passageway :28 formed in the spindle thelatter' passageway also being in constant communication with passageuavs2S) and 229 ot' the` respective spokes 5 and 5. lhen the piston otl thecylinder 13 moves toward the front end ot said cylinder, the gas willenter the rear end thereof. by suction from passageway 29 by passing thetube. 3() and check valve 31 (Figs. 1` 2). At 32 is indicated a conduitcommunicating with the rear end of cylinder 13 and with the front endot' the cylinder 14. and it is obvious that a rearward movement of the,piston ot' the cylinder 13 will cause the gas to enter the cylinder 14,said gas not heilig permitted to return, since such return will beprevented by reason of a check 'alve 33.

Hydrocarbon is conducted to the front end ot the cylinder 13 in a mannersimilar to that just described. 'hen the piston of cylinder 14 movestoward the front Aend thereof, a charge of gas. by operation ot'suction. will enter the rear end of said cylinder from passageway Q9 bypassing a tube 34 and check valve 35. A conduit 36 communicates with therear end of the cylinder 14 and with the front end ot' the cylinder 13,and a rearward movement of the piston of cylinder 14 will cause the gasto enter the cylinder 13, and by means ot' a check valve 37, the gaswill be prevented from returning.

Numerals Q8 indicate. spark plugs provided forthe cylinders, and anysuitable arrangement may be made for sparking, so that the charges ofgas in the cylinders will be ignited in alternation and at the time thegas is compressed therein, at each complete rotation of the tire. Meansare shown and will be described for Acausing ignition of gas in thecylinder 13. this being considered sufficient since the constructionIand arrangement of parts for this purpose is the same for bothcylinders. At 38 (Fig. 1) is indicated a conductor electricallyenergized by any suitable means. and adapted to electrically energize ahorizontally projecting brush 39 which is suitably'insulated and mountedon a yoke 40 carried by a block 9. Numeral 41 indicates a second brushwhich is also insulated and mounted on said yoke, this last named brushbeing` in communication with an adjacent spark plug by means J nelectrical conductor c as plainly shown in Fig. 1. By this constructionthe electrical circuit is incomplete between the brushes` 39 and 41. Byreferring to Fig. 3. It will be seen that the inner side of rthe tire isprovided with a pair of insulated contact-blocks 42 electrically incommunication by means of a conductor 43. and it will be understoodthat. during a complete rotation ot the tire. the blocks 42 carriedthereby will make contact with the brushes` 3f) and 41. this contactcompleting the electrical circuit to cause a sparking for igniting thegas within the cylinder 13.

By the construction as described the tire is provided with .a singlepair of contactblocks, and during a complete rotation of the tire saidpair of blocks are engaged by the brushes disposed near and at thefront. of both of the cylinders. whereby sparking for the cylinders isaccomplished, the piston rods moving outwardly of the cylinders inalternation, the clutches gripping and moving the ring gear, themovement of said ring gear in one direction causing the tire -to rotatein an opposite direction on account of the pairs of beveled gears 18 and19. the momentum of the tire heilig depended upon for causing a part ofits rotatable movement while not engaged by a clutch, if only twocylinders are employed, as shown.

In order that the pistons may be completely reciprocated to expelexhaust gases and 'or compressing the charges of gas. devices areprovided consisting, in part, ot' a pair of pinions 44 best shown inFig. 4, having rotatable bearings in the rim 8. Numeral 45 indicates anactuating arm or curved rack-bar disposed between and engaged by thepinions 44, said arm being mounted upon the piston rod of the cylinder13. Y

Numerals 46 indicate a pair of actuating arms or curved rack-bars (Fig.4) each being engaged by a pinion 44, said arms 46 being connected Witha yoke (Z which is mounted on the piston rod of the cylinder 14. and bythis construction it will be understood that when the piston rod ofcylinder 13 moves outwardly, the arm 45 will move in the same direction,and it will cause the pair of actuating arms 46 to move, simultaneouslytherewith, ina reverse direction to the movement of said arm 45, tothereby move the piston of cylinder 14 inwardly, this inward movementcausing the new charge. of hydrocarbon which has entered said cylinder14, to be compressed, the spent. gases having been previously expelledby the entrance of said new charge as is usual with two-cycle engines.

As thus described it will be understood that when the piston rodof thecylinder 14 moves outwardly, the pair of arms 46 will move in the samedirection. and will cause the arm 45 to move in a reverse directionasoma? to the movement of said arms 46 for moving the piston of thecylinder 13 inwardly, said inward movement causing the exhaust gases tobe expelled from the cylinder 13, and causing the fuel gas which enterstherein to be compressed. I

By referring to Figs. 2, 8 and 9, it will be seen that the exhaust gasesmay move outwardly from the cylinder 13 by entering the narrow pocketscl formed in the bottom of said cylinder, and from thence moving throughthe passageway 47 of the spoke 6, and after entering the passageway 48of the spindle, may move out of the passageway 49 of the bracket-support1, the exhaust gases from the cylinder 14 moving outwardly by passingsimilar passageways e', 47. 48 and 49.

Having fully described the several parts and their uses, a furtherexplanation relat ing to operation is not necessary.
